Be it known that I,

' Munhall, in the county of Allegheny-and State section of the same.

ing-box, showing the socket.

My invention relates to the means for detachably connecting an operatingmember,

such as the charging-bar of a machine for charging open-hearth furnaces,with a part, such as the charging-box, which is to be operated.Heretofore'these charging-boxeswere.

necessarily placed in accurate alinement with each other by reason ofthe fact that the head of the charging-bar moved downwardly into a broadvertical slot in the end of the box,- the flanges of the head fittingneatlywithin this socket, so that the-box wouldnot tilt. As.

the motions of the charging-bar are necessarily limited in character,theoperation of attaching the bar to the.boxes was a difficult and tediousone. My invention entirely overcomes thesedifficulties and enables acharging-bar tobe used'which can be moved end wise into an open-endedsocket at the end of the charging-box without the necessity of accuratealinement of these boxes, while the head of the bar is quickly andeasily secured to or disengaged from the box-socket.

In the drawings, in which similar numerals indicate corresponding parts,2 represents the casting forming the end of a charging-box,

this casting having an open-ended socket of general rectangular form,with its side 3 inclined or beveled outwardly, as shown. The

head l of the charging-bar 5 is provided with inclined faces 6,; whichare anr'anged to slide over the inclined faces 3 of the charging-boxsocket and fit neatly within such socket.

This head is provided with a horizontal slot 7,

fwithin which are pivoted levers 8, said levers ALVA O. DINkEY, of,

operated by a wedge Fig. 3 is a partial hori-' zontal section of amodified form'of mechan-, ism; and Fig. 4=.is an endvie-w of thecharg IApplication filed February K0. 624,686- (No model.)

a rod 12, which passes longitudinally through the charging-bar and maybe operated by an Ihaving'locking projections 9, arranged toenter'recesses 10 in the end faces of the socket. In the form of Figs. 1and 2 the levers 8 are u 11, secured tothe end of electric motor, ahydraulic cylinder, or any other suitable means. A second wedge 13 maybe provided, which acts upon the rearv ends of the levers 8 topositively move their outerendsinwardly, though this is not essential.Ijinay-useother means for operating these levers-such, for instance, asthetog'glelinks 14 0f 'Fig. 3-'-which pivotally connect the levers 8'with the end of the operating- The operation of the device is apparent.

The boxesare placed on a suitable support and do not need to beaccurately alined since the end of the charging-bar as it enters thesocket by sliding over the inclined faces will move this end of the box,so as. to allow the entrance of the charging-bar head. I The 1ever's 8then being moved outwardly by the wedge 01 other device therefor, thehead and thehox are locked together, so that the box may be carried intoand out of the furnace and turned at any point.

The ad vantages of the Invention result from the fact that fewermovements'of the charging-bar are needed, since its head movesendwisedirectly into the open-ended socket, and

the head itself as it enters the socket will bring the box into properposition for lockmg; to the box are easily performed, and the wholedevice is of few parts and not liable to get out of order. 3 1 Manyvariations in the form,constructi0n, and relative arrangement of theparts of my device may be made by the skilled mechanic The lockingand'unlocking of the head without departure from .my invention, sinceWhat I claim is- 1. The combination with an element having at one end anopen-ended socket, of a movable bar having a head arranged to moveendwise directly into the socket, and a look ing mechanism arranged torigidly connect the .bar and socket.

2. The'combination with an element to be operated, having, at one end anopen-ended socket with inclined inner faces, of a bar movable endwisedirectly into the socket and having a head provided with inclined facesarranged to slide over the inclined faces of the socket and fit therein,a locking mechanism arranged to rigidly lock the head to the socket, andmeans for unlocking the head in any position of the element.

3. The combination with an element, having at one end an open-endedsocket, of a bar having a head movable endwise directly into the socket,lockinglevers in the head. arranged to engage recesses in the sidesofithe socket and rigidly lock the head therein and means for positivelymoving said levers to lock or unlock the head in any position of theelement.

4. The combination with a charging-box, having at one end an open-endedsocket provided with inclined inner faces, of a charging-bar having ahead provided with inclined outer faces arranged to fit within thesocket,

locking-levers pivoted within the head and myhand.
